All of the above
n-propyl alcohol and iso-propyl alcohol are examples of
position isomerism
chain isomerism
tautomerism
geometrical isomerism
Optical isomerism is shown by
butanol-1
butanol-2
butene-1
butene-2
B.
butanol-2
The necessary and sufficient conditions for a molecule to show optical isomerism are:
(i) Compound must contain atleast one asymmetric carbon atom.
(ii) Compound has no plane of symmetry.
(iii) Compound should be non-superimposaale on its mirror image.
Butanol-2 shows optical isomerism due to presence of one asymmetric carbon atom.
Heating together of sodium ethoxide and ethyl iodide wll give
ether
ethyl alcohol
acetaldehyde
acetic acid
One mole of a solute A is dissolved in a given volume of a solvent. The association of the solute takes place according to nA [A]n. The van't Hoff factor (i) is expressed as:
i = 1 - x
i = 1 +
i =
i = 1
